Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of UPVC pipe processing, in particular to a feeding device for producing UPVC pipes. Background Art
[0002] UPVC pipes are plastic pipes made of polyvinyl chloride (PVC) resin. They not only have the properties of general polyvinyl chloride, but also have the advantages of being free of plasticizers, non-toxic, corrosion-resistant, flexible, and not prone to electrochemical reactions with acids, alkalis, and salts. They are widely used in water supply networks. UPVC is not heated evenly and stably in the feeding device. After UPVC is heated into a molten state, its internal molten state is also uneven.
[0003] After searching, the Chinese patent "Front-end feeding device for producing UPVC transparent pipes" with the announcement number "CN216914518U" was found. In order to solve the above problems, the patent adopts the setting of a separation pipe to separate the feeding pipe into a preheating part, a heating part and a heat preservation part, and sets electric heating wires on the surface of the heating part and the preheating part to preheat the UPVC material first and then heat it, so that the UPVC material is heated more evenly, and then cooperates with the rotation of the spiral conveying blade 1, the spiral conveying blade 2 and the spiral conveying blade 3 to make the UPVC material be transported to the left side. At the same time, it is stirred, which further enhances the uniformity of heating of UPVC. However, when melting the raw materials, the device will first melt the raw materials in contact with the inner wall of the feeding pipe, and the raw materials close to the rotating shaft melt at a slower speed, which can easily cause uneven melting of the raw materials in the feeding pipe. Moreover, the device directly heats the surface of the feeding pipe, and there are multiple vacant positions between the multiple heating structures on the surface of the feeding pipe, so that the surface of the feeding pipe is directly exposed to the air, which can easily cause heat loss on the feeding pipe, further increasing the uneven melting of the raw materials.
[0004] Therefore, a feeding device for producing UPVC pipes is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a feeding device for producing UPVC pipes in order to solve the above problems, thereby improving the problem of uneven melting of raw materials in the feeding pipe when the device melts the raw materials.
[0006] The utility model achieves the above-mentioned purpose through the following technical solutions.

[0008] Preferably, the surface of the feeding tube is fixedly connected with equidistantly distributed stirring sleeves, and the stirring sleeves are arranged on the surface of the heat-conducting rod. The stirring sleeves located on the surface of the heat-conducting rod will rotate with the rotation of the rotating tube, so that the heat-conducting rod can be protected while stirring the raw materials, so that the heat-conducting rod can contact more raw materials, further improving the uniformity of the raw materials after melting.
[0009] Preferably, a separator tube is fixedly connected to the inner wall of the rotating tube, and a retaining ring is fixedly connected to the surface of the separator tube. The surface of the retaining ring is fixedly connected to the inner wall of the rotating tube. The separator tube can block the raw materials that have just entered the feeding tube to a certain extent, and the retaining ring can block the melted material, thereby solving the problem in the comparative patent that the melted material flows to the angle between the separator tube and the feeding tube and is difficult to discharge.
[0010] The beneficial effects of the utility model are:
[0011] 1. When conveying materials, the electric heating tape is energized to heat the surface of the feeding pipe, and then the heat is passed through the feeding pipe to heat and melt the raw materials in contact with the inner wall of the feeding pipe.
